The Atlas Scientific EZO™ RTD Temperature circuit is a small footprint computer system that is specifically designed to be used in robotic applications where the embedded systems engineer requires accurate and precise measurements of temperature through a generic PT-100/PT-1000 temperature probe.

Features

Reads

Extreme sensing range from -126.000 °C to 1254 °C

Accurate temperature readings down to the thousandths place (+/- 0.002)

Automatically detects if probe is PT100 or PT1000

Temperature output in Celsius, Kelvin or Fahrenheit

On-board data logger storing up to 50 individual temperature readings

Optional single point calibration

Single reading or continuous reading modes

Data format is ASCII

Isolation not needed

Two data protocols

UART asynchronous serial connectivity

(RX/TX voltage swing 0-VCC)

I2C (default I2C address 0x66)

Compatible with any microprocessor that supports UART, or I2c protocol

Operating voltage: 3.3V to 5V

Reads temperature from any off-the-shelf PT100 or PT1000 temperature probe
